Abstract

The mechanisms of charge accumulation and relaxation in electrically insulating films of cross-linked polyethylene prior to and after thermal aging are studied using the method of thermostimulated depolarization currents. It is demonstrated that the stability of the electretic state in samples of silane cross-linked polyethylene is higher than that in samples of peroxide cross-linked polyethylene. The spectra of currents are analyzed by mathematical modeling. The mechanisms of charge relaxation in films of cross-linked polyeth-ylene are determined.
